I'm hearing too many people say that the aftermarket cats don't last long. Or that the aftermarket cats are not meant to be on the Tacoma, so if you have a check engine light on then putting an aftermarket cat won't clear it because the sensors or electronic system won't match it correctly.
The price difference is what makes me second guess what I should do. What I want is a product that will last and do the job. So if that means spending more on an OEM cat then I'm fine with that. Just thought I'd ask for the opinion and experience from others.
Also, if I go with an OEM cat, am I able to just switch it out or should I take it to a muffler shop?
Last question... Is there 1 or 2 cats on a 2001 3.4L Tacoma. I've been told there are 2, but also reading other people posts about how their truck is under California emissions so they have 2 cats. I'm in Austin, Texas so I'm not sure if mine should have 1 or 2. I took a look the other day and it looked like there were 2 cats. But then I looked online at Toyota.com and the diagram on their website said the 3.4 only has 1 cat. So I'm kind confused as to how many cats my truck has and actually needs to have in order to pass emmissions testing here in Austin.
Thanks for y'all's help!!!!!!!
